The bond order in \[CO_{3}^{2-}\] ion between \[C-O\] is

A) Zero                            

B) 0.88

C) 1.33                            

D) 2

Correct Answer: C

Solution :

We know that carbonate ion has following resonating structures Bond order \[=\,\,\,\frac{Total\text{ }number\text{ }of\text{ }bonds\text{ }between\text{ }atoms}{Total\text{ }number\text{ }of\text{ }resonating\text{ }structure}~~~\] \[=\,\,\,\frac{1+1+2}{3}=\frac{4}{3}=1.33\]
